Issues with import and export between Revit Architecture 2008 and 3ds max 2008:
Polymesh export:
If the Revit file is exported as a polymesh, the 3D shape is made up of multiple 2D polygons that are joined together to form the 3D shape to form a face based mesh geometry. the geometry can be edited with respect to individual faces and can be assigned different materials.
Polymesh geometry
ACIS solids export:
If the Revit file is exported as an ACIS solid, in this format each 3D shape becomes a single shape. It does not consist of polymesh objects, and thus cannot be edited like a polymesh objects.
Tips:
Which format to export? The best practice is to decide beforehand about how the project is going to be handled in Max. if the final view requires different textures and materials (generally an interior scene) for a single element, it is better to use the Polymesh option.
The geometry does not look right! Check the layer settings while importing the file in Max and remove any duplicate geometry. Try using the other format and different versions of dwg format.
Texture issues:
Revit Architecture 2008 does not have a very good texture support while exported to 3ds max as they share different type of material library and render engines (Accurender for Revit and Mental ray for Max). Hence, the best practice is to reassign the materials and texture in Max by picking up the scene materials and modifying them.
